| Abstract: | In order to verify the factuality of the old and new optimal formulas of the throwing angle in shot put, the marking of the optimal angle of release was applied to sample for verifying the old and the new formulas. It was concluded that the new formula fits the practice well, while the traditional one deviates seriously from it. The marking of the new formula enables the athletes to precisely and objectively grasp the best angle of release, suitable to the athlete him/herself. It was suggested that the traditional optimal formula of the throwing angle mentioned in the track & field teaching material should be replaced by the new one. |
